(ci. 98-42) The present invention relates to roof ventconstruction for housings, especially of the character which aresuitable to house machinery or equipment, but permissibly also tohousings which are intended to provide special buildings, huts or thelike.

The present application is a division of our copending applicationSerial No. 168,376, tiled January 24, 1962, for Housing and copendingapplication Serial No. 429,550, filed February 1, 1965, for BuildingStructure.

A purpose of the invention is to produce a roof vent for a housing whichcan be very readily transferred in compact form to a site for erection.

A further purpose is to improve the structure for ventilating thehousing.

A further purpose of this invention is to provide a roof ventconstruction of increased structural strength with resistance to windageand corrosion.

Further purposes appear in the specification and in the claims.

Describing in illustration but not in limitation and referring to thedrawings:

There is considerable need for a housing which can United States PatentO 3,257,932 Patented June 28, 1966 rice be shipped in folded or knockeddown condition to any part of the world, including the Arctic, orAntarctic and also including remote and inaccessible locations, forcovering and protecting machinery and equipment such as turbines,engines, generators, radar equipment, scientific measuring equipment andthe like. The housing lends itself to such service, both in cases ofmilitary installations; also for scientific expeditions, and in somecases for normal civilian uses. This invention relates to a ventilatorconstruction for such housings.

One of the great advantages of the ventilator of the invention is thatthe elements of the ventilator `are themselves relatively light, andalso are not bulky. They can be shipped or transferred or hand carriedto the site and installed readily with a minimum of tools.

,The structure is primarily of aluminum alloy, and is designed to resistthe elements and has very high resistance to corrosion in variousenvironments. The structure also is designed to withstand adverseconditions, which -may be encountered, for example, in the Arctic andAntarctic, such as windsof 135 miles per hour, and various atmosphericconditions, such as snow, sleet, ice and hail. Provision has been madefor excellent ventilation, to carry olf any gases generated by themachinery `or equipment, and to provide comfortable working conditionsfor personnel.

The ventilator housing is essentially constructed out of a plurality ofsnap-in metallic extrusions with appropriate supporting means. Forfurther discussion on the construction of these metallic extrusions,reference is made to our above-identified copending application forHousing.

Referring now to the drawings in detail, the housing consists offootings 40 on which are supported side walls 41, end walls 42, a roof43, and Ventilating assemblies 44, which are described more in detaillater.

As best seenin FIGURE 1,each end of the housing has an access opening94, which may be closed by a suitable door if desired.

At intervals suitably on either side of the end walls 42, there areprovided doors 103 and at suitable places in the side walls there areprovided doors 104.

At a central point in each of the oppositely sloping roof panels of a'pair, it is desirable to locate a ventilator. Openings 146 are suitablypunched in Vthe webs of lthe extrusions 57 forming the roof beneath theventilator as best seen in FIGURE 2. Centrally located at eachventilator is placed a suitable rectangular collar 147 which consists ofa web 148 desirably thickened toward the bottom, a transverse bottomflange 150 and an outwardly aring top flange 151. There is an inwardlyextending intermediate rib 152 from the web. The sections of theextrusion 147 are mitered at the corners and the rib 152 A is cut awayat 153 near the corners to receive an upwardly extending angle 154 bestSeen in FIGURES 2 and 6 which is secured to the collar 147 as by rivets155. 'I'he collar 147 is fastened to the roof panel by bolts 156 withcaulking if desired.

The collar 147 is desirably braced by cross braces 157 secured totheribs 152 as by rivets 158, best been in FIG- `URE 16. The angleuprights 154 extend considerably above the top of the collar and at thetop there are suitably mounted, as by welding, nuts best seen in FIG-URES 2 and 3. The cap or cover for the ventilator 44 consists ofsupporting angles 161 extending .transverse to` the ridge of the roof,resting on the nuts 160, and secured at the ends as by welding tobrackets 162. The top and the two sides of the cover consist of suitablealuminum snap-in extrusions 163 best seen in FIGURES 2 and 4 andconsisting of webs 164 which have at one edge female socket sectionsincluding flanges 165, 166 and 167, which 3 are generally in the shapeof an inverted trapezium. Near the edge toward the web 164 there is aprojection 168 which ts into an interlock recess 170 at the opposite endof the web 164. Adjoining the interlock recess 170 on the end of the webis a projection 171 following the inside of the trapezium shape of theflange 165 and having an angularly bent rib 172 at the end whichinterlocks within a rib 173 on the trapezium flange 165.

A rib 174 from the web fits immediately inside the trapezium ilange 167of the next extrusion, so that by deecting the extrusions they can besnapped together as shown in FIGURE 2.

At front and back corners an extrusion is provided which resembles theothers but has a curved web 164 as best seen in FIGURE 2.

The corresponding extrusions 163 and the angles 151 are bolted to thenuts 160 at the uprights 154 by bolts 175 extending through theextrusions and through spacers 176 and then through the angle 161 andinto nut 160.

At the ends of the extrusions 153 brackets 177 are secured to theextrusions as by rivets 178, and the brackets support extrusions on thesides of the cover which are connected to the brackets by rivets 180. Atthe top of the sides the webs are suitably cut olf at 181 and at thebottom special cooperating snap-in extrusions 182 are suitably usedhaving ribs 183 at the extreme bottom edges. The

same is true of the `bottoms of the front and back portions as shown inFIGURE 2.

At the center of the roof panel, as best shown in FIG- URE 4, there is ametallic extrusion having female socket sections at both ends. Thispermits reversal of the order of the extrusions so that the specialbottom snap-in extrusion 182 can be secured to both ends of the sidepanels.

As best seen in the FIGURE 2, the bottom of the cover terminates justbelow the outer flaring portion 151 of the collar but at a considerabledistance outwardly thereof so that gas flowing upwardly as shown by thearrows 184 will pass through the openings 146 .and through the spacewithin the collar 147 and then will pass downwardly in the space betweenthe bottom edge of the cover and the roof as suggested by arrows 185 and186.

The ends of the extrusions forming the top of the cover are suitablyconnected to the extrusions at the sides by an extrusion 187 which has aweb 188 running along the ends of the extrusions at the top and a ange190 joined to the extrusions at the top by rivets 191, and a ange 192extending under the extrusions 163 and then an angle ange 193 joined tothe top-most side extrusion by rivets 194.

In some cases it is not suflcient to rely on natural ventilation and inFIGURES to 12 we illustrate a modied Ventilating assembly.

In this case an opening 195 suitably of circular form is cut in thecover extrusions 57, and a rim 196 is secured by rivets 197 to `tinishthe inner edge of the opening. The collar 147 is constructed as beforeand provides the uprights 154 at the corners which are to connect to thecover.

Secured to the `roof extrusions for bracing purposes on the sides areangles 198 anchored by rivets ,200 to brackets 201 secured by rivets 202to the extrusions 163.

On top of the roof but under the cover is provided a frame -203 which issecured to the roof extrusions 57 at 204 and which has mounted thereonan electric motor 20S provided with a shaft 206 and pulley 207 whichconnects by a belt 208 with a pulley 210 on shaft 211 joumalled onbearings 212 in the frame carrying an exhaust fan impeller 213.

It will be evident that the fan will draw air through the opening in theroof and discharge it in the space between the ventilator cover and theroof.

In view of our invention and disclosure variations and modifications tomeet individual whim or particular need will doubtless become evident toothers skilled in the art, to obtain all or part of the benefits of ourinvention without copying the structure shown, and we, therefore, claimall such insofar as they fall within the reasonable spirit and scope ofour claims.
